Abstract

Landwirtschaftliche Feldspritze mit zumindest einem Flüssigkeitstank (1), zumindest einer Pumpe (2) mit zumindest einer Zuleitung, zumindest einer zumindest ein Druckregelventil (4) aufweisenden Dosierarmatur, zumindest einer in den Flüssigkeitstank (1) einmündenden Rücklaufleitung (15) und zumindest einer sich in mehrere Spritzleitungen (7,7') verzweigenden und zumindest eine von einem Bordrechner (17) einstellbare Dosierarmatur aufweisende Druckleitung, wobei die Spritzleitungen jeweils zu Ausbringdüsen eines Verteilergestänges führen, wobei die Flüssigkeitszufuhr zu den Ausbringdüsen über in den Spritzleitungen angeordneten und von einer Abschalteinrichtung (5,6), die vorzugsweise von dem Bordrechner ansteuerbar ist, betätigbaren Abschaltventilelementen zu- und abschaltbar sind. Um insbesondere für die Einsatzzyklen, bei denen mehrere oder alle Teilbreiten der Spritzleitungen zu- oder abgeschaltet werden eine verbesserte Handhabung der Einstellung des Flüssigkeitsstromes zu schaffen, ist vorgesehen, dass von der Druckleitung (9) zwischen dem Druckregelventil und den Abschaltventilelementen eine in die die Zuleitung und/oder den Flüssigkeitstank einmündende Abzweigleitung abzweigt, dass in der Abzweigleitung (20) ein zu öffnendes und zu schließendes und vom Bordrechner und/oder der Abschalteinrichtung ansteuerbares Absperrventil angeordnet ist, dass in Durchflussrichtung (23) gesehen hinter dem Absperrventil (21) ein vorzugsweise einstellbares Druckbegrenzungsventil angeordnet ist.
